 2002 AA29 - Wikipedia, the free encyclopedia
Asteroid 2002 AA also written 2002 AA29) is a near-Earth asteroid discovered in January 2002 by the LINEAR asteroid survey.
Richard Gott and Edward Belbruno from Princeton University have speculated that 2002 AA might have formed together with Earth and Theia, the postulated planet that, according to the Giant Impact theory collided with Earth in its early history.
The orbit of the asteroid is such that it would be relatively easy for a spacecraft to retrieve rock samples from it and bring them to Earth for analysis.

 Earth Coorbital Asteroid 2002 AA29
Coorbital asteroids similar in some ways to 2002 AA29 are known to follow Jupiter's orbit and Mars' orbit, but this is the first one known for Earth.
Asteroid 2002 AA29 was discovered by the LINEAR asteroid search program in January 2001.
Note that we are looking at the asteroid from above the Sun, and in a frame which moves along with the Earth, which remains stationary at the bottom of the frame (for an animated view, see the MPEG movie clip).

Asteroid 2002 AA29 is only about 100 metres wide and never comes closer than 5.8 million kilometres (3.6 million miles) to our planet.
This puts 2002 AA29 is in the same class as 3753 Cruithne, a similar rocky body in a horseshoe orbit around the Earth.
It is clear that 2002 AA29 was discovered by accident at a time when it was at one end of its horseshoe orbit and, being at its closest to the Earth, was bright enough to be detected in an automated sky survey.

 Rendezvous with Earth Co-Orbital Object, Asteroid 2002 AA29   (Site not responding. Last check: 2007-11-04)
AA29 is in a ‘horseshoe’ orbit - meaning that it closely follows Earth’s orbit, then turns around when it gets near the Earth and follows Earth’s orbit in the reverse direction.
AA29 approaches the Earth on its leading side because of its slightly larger semi-major axis, which results in a smaller mean motion.
AA29 possess an exceptional opportunity for scientist to ascertain the composition of an asteroid in a relatively cost-efficient mission.

The asteroid, called 2002 AA29, is in a precise circular orbit that follows the same general path as the Earth around the sun.
Even if 2002 AA29 did hit the Earth, it would not cause planetwide destruction as did the 10km-wide asteroid that hit and killed the dinosaurs some 23 million years ago.
Asteroid observations are among the 1000 studies to be presented this week at the national meeting of the American Astronomical Society.

Asteroid 2002 AA29 is like a mouse teasing a cat, approaching Earth first on one side and then on another, without ever making contact or actually passing our planet as the two bodies circle the sun, say astronomers.
This particular asteroid is the first ever found to orbit the sun in nearly the same path as Earth, but never manages to pass it, the National Aeronautics and Space Administration said.
In 95 years, the asteroid will have advanced all the way around to where it is catching up to the Earth from behind.

 Independent, The (London): Meet asteroid 2002 AA29: or Earth's `little brother'
Asteroid 2002 AA29, a 100-metre-wide lump of space rock, was discovered by a team of astronomers led by Martin Connors of the Centre for Science at Athabasca University in Canada.
Duncan Steele, an expert on asteroids at Salford University, said the asteroid's orbit is similar to the circular path that Earth follows once each year around the Sun.
Dr Steele said that if the asteroid were composed of iron and nickel it could prove invaluable for future space missions, who could use the mineral deposits.

 Near-Earth Asteroid 3753 Cruithne
The near-Earth asteroid 3753 Cruithne is in an unusual orbit about that of the Earth, one which is known in the lingo of celestial mechanics as being co-orbital with the Earth (meaning it shares the Earth's orbit with it) and, more particularly, as being of the "horseshoe" type.
The apparent overlap of the asteroid with the Earth does not result in any danger of collision because the asteroid's orbit is highly inclined to that of our planet.
Though the asteroid thus appears to orbit the Earth, this is a result of the frame of reference we are using.

Orbit studies by Paul Chodas, a Jet Propulsion Lab engineer, show that in about six hundred years, the Earth will force the asteroid to make a complete orbit around the Earth and then make it a small Moon, continually circling the Earth for about forty years.
